Each data encryption standard was developed to meet different security needs. For this reason, many data encryption services have adapted to using asymmetric algorithms.īeyond the symmetric and asymmetric distinction, there are several methods of encryption and handling secure data in practice today. This in turn has led to massive numbers of keys for organizations to manage securely-a growing problem.
Symmetric-key encryption is quicker than asymmetric encryption, but before decryption can take place, it requires the sender to exchange the encryption key with the recipient. A private, unshared key that must remain protected decrypts the data. Asymmetric encryption, sometimes referred to as public-key encryption or public-key cryptography, uses two keys for encryption and decryption.
In symmetric encryption, a single, private password both encrypts and decrypts data. There are two main kinds of data encryption: symmetric encryption and asymmetric encryption.
